Questions buyers ask
- Can AiP1638 replace TM1638?
- AiP1638 is I-CORE's functional equivalent of TM1638 in the same SOP-28 package. Standard parts in this family share the industry pinout, but please compare both datasheets — supply range, timing and absolute maximum ratings — before design-in.
- What is the supply voltage and temperature range of AiP1638?
- Supply: See datasheet. Operating temperature: See datasheet. See the datasheet for full electrical characteristics.
- Is AiP1638 in stock, and can I get a free sample?
- Yes, it is held in stock in Shenzhen. Free samples are available for evaluation, with shipping paid by us. For production orders, SMD parts can be ordered from 1 pc and DIP parts ship in full tubes; orders ship within 2–3 business days after payment.
- Is it original I-CORE product?
- Yes. We supply factory-original I-CORE (Wuxi I-CORE Electronics) parts in sealed reels and tubes. Our ISO 9001, ISO 14001 and ISO 45001 certificates are shown on the home page; RoHS and REACH test reports are available on request.
Datasheet highlights
From the I-CORE English datasheet AiP1638 (revision 2024-11-B1). The full datasheet PDF is linked above.
General description
AiP1638 is an LED Controller driven on a 1/8 duty factor.10 segment output lines,8 grid output lines, one display memory, control circuit, key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to AiP1638 via a three-line serial interface. Housed in a 28 pins SOP package, AiP1638 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
